Nick Coghlan <ncogh...@gmail.com> added the comment: The alternatives are a backwards compatibility break (i.e. raise exc from other_exc would suppress the context, but exc.__cause__ = other_exc would not) or else that we don't succeed in eliminating the dual use of __cause__ in the display routines.
Given that those two problems are the reason I went for the PEP 409 approach in the first place, I'm really only interested in alternative approaches that eliminate them (such as setting the flag automatically whenever __cause__ is set). If you don't like it, then we already have PEP 409's Ellipsis based implementation which meets my criteria. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14133> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
